Raymont "Tony" Nelson testified that the conversation happened at the home of defendant Ronald Robinson's mother, while the man's mother was there.

Robinson said he went to a house on Johnston Road to collect his money and shot a man who was inside, according to Nelson's testimony.

Nelson testified that Robinson said he went outside, and a police officer was there who told him to freeze, and he shot the officer.

He testified that he asked Robinson, "Why would you do something stupid like that? Do you want to spend the rest of your life in jail?"

Another witness testified that Robinson was out of breath and seemed agitated, talking to himself and to others on a cellphone, when he returned to a Steelers party after he briefly left.

"I told him not to mess with me about my money, I told him, I told him," Robinson said, according to the witness.

Robinson is charged with two counts of homicide for the deaths of Crawshaw and Danyal Morton. He could get the death penalty if a jury finds him guilty. (SLIDESHOW: Photos from the Crawshaw police funeral)
